sag mill explanation

Principle of SAG Mill operation. SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%.[6][7] The largest SAG mill is 42′ (12.8m) in diameter, powered by a 28 MW (38,000 HP ...

On dry SAG mills end liners: Physical modeling, DEM …

In designing AG and SAG mills, especially dry SAG mills, the effective mill length is one of the basic parameters. In Aerofall mills, the grinding chamber length is short due to limitation of air stream in carrying out the ground material. It is then logical to expect that the end liners do not reduce the effective mill length.
